* Parameters: Now correctly implements _flatten_() method and flag.
...
- The _flatten_() method should recursively flatten the parameter
search space into a single dict.
- The _flatten_ flag will flatten the input dicts and keyword-based
parameter (in the __init__() method only) in the expected order of
priority (where the first found keyword is the most overriding one)
into a single search dict.

* text_input.read_items(): added option `end_line_match' and `last_line_match'
...
(mutually exclusive options) to allow the dataset reading to end upon
encountering certain text pattern (or a more complicated match, if we
specify a function for the option value).
These options can be used to work with the `maxcount' option; the shortest
of the two (maxcount records read first, or end/last_line_match finds a
match) will end the reading of the dataset.

...
implemented as a generator rather than yielding the list right away.
